San Francisco 49ers quarterback Colin Kaepernick figures to give Atlanta Falcons fans fits as they prepare for Sunday's NFC championship game. Stopping him — and how to do it — will likely keep Falcons coaches and players await late heading into the game.

Aikman watched as Kaepernick tore apart the Packers. His advice: Discipline on defense is the starting point for the Falcons.

"There are certain rules you have to stick with it you are going to be effective against a quarterback that can run like that," Aikman says. "A number of Colin's runs were because of scrambles."

While there were designed running plays, Aikman says it's vital for the Falcons to pay attention to Kaepernick when he is on the move. It's also critical for coverage to remain consistent.

Other issues ahead for the NFC championship game:

— Falcons pass rushers must not get overly aggressive. That would prevent running lanes from opening that Kaepernick can exploit. The Falcons will want Kaepernick to pass, not get free for running yards.

— Matt Ryan and the Falcons gained confidence by finally getting their first playoff victory. Result: Expect them to be looser.

In the AFC title game, Aikman says Ray Lewis continues to inspire the Ravens, especially with a desire to send him out with a second Super Bowl victory. But observers can't overlook other players' drive to prove themselves. In particular, Aikman points to quarterback Joe Flacco.
